Yes they were probably under geared i guess. I was soloing it fairly easily with just half a build.
Levelling a tank to 50 can feel very underwhelming when a brute can tank pretty much the same, especially with a few buffs, yet kill so much faster. I just thought whats the point? and rolled a brute, so much easier.
A brute can easily match the survivability of a Tanker or come very very close, yet a Tanker is not even close to brute damage on live. Nerf Brutes a little so tankers only need smaller buffs or just raise the Tanker damage to nearer Brute damage. A brutes damage can stay the same but its survivability caps should be lowered slightly to somewhere between scrapper and Tanker, its a little too close to tanker survival with Io's and buffs in my opinion.
Something like this.....
Brute 9/10 damage 8.5/10 survival
Scrapper 10/10 damage 7.5/10 survival
Tanker 7/10 damage 10/10 survival
